変動費
Meaning: Variable expenses that fluctuate month to month — food, entertainment, clothing, and discretionary spending.
変動費 is the counterpart to 固定費 in Japanese personal finance discussions. While 固定費 reduction is considered the 'smart' first step, 変動費 management requires ongoing discipline and is where most day-to-day budgeting happens. Japanese finance content often debates whether it's better to aggressively cut 変動費 or focus on increasing income. Common 変動費 categories include 食費 (food), 交際費 (socializing), 被服費 (clothing), and 趣味費 (hobbies).
Examples
- 変動費の中で一番多いのが食費だから、自炊増やすことにした。 可变支出里花最多的是伙食费,所以决定多自己做饭。Lo que más pesa en mis gastos variables es la comida, así que decidí cocinar más en casa.변동비 중에서 가장 큰 게 식비라서, 자취 요리를 늘리기로 했어.
- 変動費は月によって全然違うから管理が難しいんだよね。 可变支出每个月差别很大,管理起来真的很难。Los gastos variables cambian totalmente de un mes a otro, por eso es difícil controlarlos.변동비는 달마다 완전 다르니까 관리가 어렵지.
- 固定費は削れたけど、変動費がコントロールできなくて結局トントン。 固定支出是砍下来了,但可变支出控制不住,结果还是白搭。Conseguí recortar los gastos fijos, pero no logro controlar los variables y al final quedo igual.고정비는 줄였는데, 변동비를 컨트롤 못 해서 결국 도긴개긴이야.

✓ Do Say
- 変動費は家計簿つけないと把握できないよ。 (You can't track variable expenses without keeping a household budget.)可变支出不记账根本把握不了。No puedes controlar los gastos variables si no llevas un registro de la economía doméstica.변동비는 가계부를 안 쓰면 파악이 안 돼.
- 変動費を無理に削ると生活の質が下がるから注意。 (Be careful about cutting variable expenses too hard — it lowers your quality of life.)可变支出砍太狠会降低生活质量,要注意。Cuidado con recortar demasiado los gastos variables: baja la calidad de vida.변동비를 무리하게 줄이면 삶의 질이 떨어지니까 주의해야 해.
✗ Don't Say
- 「変動費ゼロにすれば?」は非現実的 (Suggesting someone reduce variable expenses to zero is unrealistic — everyone needs food, transportation, and some leisure)建议别人'把可变支出降到零'是不现实的——每个人都需要吃饭、交通和基本的休闲Sugerir «¿por qué no reduces los gastos variables a cero?» es poco realista: todo el mundo necesita comida, transporte y algo de ocio.'변동비를 제로로 만들면 되잖아'는 비현실적 — 식비, 교통비, 최소한의 여가는 누구에게나 필요하다
Common Mistakes
- Treating all 変動費 as wasteful — some variable expenses (healthy food, necessary socializing) are important investments in well-being
